The first, industry made, model magnet for the CERN Large Hadron Collider

The first magnet model for the LHC (Large Hadron Collider) is a single-aperture, 1-m-long, dipole magnet based on NbTi cable technology and designed for an 8-T nominal field at 2 K. It reached and passed its nominal field without any quench and attained 9.1 T, where it operated without quenching before the first campaign of tests was voluntarily stopped. In a second test campaign a 9.3 T central field was attained. After a description of the magnet, the authors discuss the cable characteristics, manufacturing tools, and magnet performance.<
